4f1f149c37 Fix the clang build: this compiler doesn't support the gnu_inline function attribute
Recent clang compiler doesn't have gnu_inline working. When frameworks/rs
is compiled with clang instead of gcc, it no longer works. Will be fixed
by this patch.

In particular this affects assert(3) and __cxa_pure_virtual, both of
which have managed to confuse people this week by apparently aborting
without reason. (Because stderr goes nowhere, normally.)

c20d0f3993 Correction to use of TEMP_FAILURE_RETRY in send_prop_msg
RETRY macro may retry command if result is -1. In this
case the command was "connect < 0" instead of just
connect. The comparison will not return -1 and thus
retry is never done. This is now corrected so that
interrupts will cause retry instead of fail.

(There was no other negative side effect of the bug.
The result code from RETRY was used in an if-statement
and it would be true for all negative connect results.
This was according to expectations.)

The factory file (and Factory time zone) was meant as a way to say

For us it would just look like UTC, so it is of no value.

5d967e43d0 Upgrade to tzdata2012d.
This upgrade involved rewriting the script; the data has moved to ftp.iana.org,
where it's slightly less convenient to access, so it's time to use something
that can talk FTP...

As for tzdata2012d, it's just updating Morocco for this weekend's changes, now
they've been decided at the last minute (as usual).

260bf8cfe0 FORTIFY_SOURCE: strlen check.
This test is designed to detect code such as:

int main() {
  char buf[10];
  memcpy(buf, "1234567890", sizeof(buf));
  size_t len = strlen(buf); // segfault here with _FORTIFY_SOURCE
  printf("%d\n", len);
  return 0;
}

or anytime strlen reads beyond an object boundary. This should
help address memory leakage vulnerabilities and make other
unrelated vulnerabilities harder to exploit.

b2060b027c FORTIFY_SOURCE: restore __memcpy_chk()
In our previous FORTIFY_SOURCE change, we started using a custom
inline for memcpy(), rather than using GCC's __builtin_memcpy_chk().
This allowed us to delete our copy of __memcpy_chk(), and replace it
by __memcpy_chk2().

Apparently GCC uses __memcpy_chk() outside of __builtin_memcpy_chk().
Specifically, __memcpy_chk() is used by __builtin__memMOVE_chk() under
certain optimization levels.

Keep the old __memcpy_chk() function around, and have it call into
__memcpy_chk2().

f3913b5b68 FORTIFY_SOURCE: enhanced memcpy protections.
Two changes:

1) Detect memory read overruns.

For example:

int main() {
  char buf[10];
  memcpy(buf, "abcde", sizeof(buf));
  sprintf("%s\n", buf);
}

because "abcde" is only 6 bytes, copying 10 bytes from it is a bug.
This particular bug will be detected at compile time.  Other similar
bugs may be detected at runtime.

2) Detect overlapping buffers on memcpy()

It is a bug to call memcpy() on buffers which overlap. For
example, the following code is buggy:

  char buf3[0x800];
  char *first_half  = &buf3[0x400];
  char *second_half = &buf3[1];
  memset(buf3, 0, sizeof(buf3));
  memcpy(first_half, second_half, 0x400);
  printf("1: %s\n", buf3);

We now detect this at compile and run time.

e64259e860 memmove: Don't call memcpy if regions overlap
memmove() unconditionally calls memcpy() if "dst" < "src". For
example, in the code below, memmove() would end up calling memcpy(),
even though the regions of memory overlap.

int main() {
  char buf3[0x800];
  char *dst  = &buf3[1];
  char *src = &buf3[0x400];
  memset(buf3, 0, sizeof(buf3));
  memmove(dst, src, 0x400);
  printf("1: %s\n", buf3);
  return 0;
}

Calling memcpy() on overlaping regions only works if you assume
that memcpy() copies from start to finish. On some architectures,
it's more efficient to call memcpy() from finish to start.

This is also triggering a failure in some of my code.

6334c662ca Don't use -fstack-protector on ssp.c
libc's stack protector initialization routine (__guard_setup)
is in bionic/ssp.c. This code deliberately modifies the stack
canary.  This code should never be compiled with -fstack-protector-all
otherwise it will crash (mismatched canary value).

Force bionic/ssp.c to be compiled with -fno-stack-protector

Fix unnecessary call to __open_2. If, at compile time, we know that
"flags" is constant and DOESN'T contain O_CREAT, the call to __open_2
is useless.

normally do.
